I have a local breeder in Illinois who supplies many Pet Stores and a few big chain Pet Stores like Petsmart or Pet Supplies , He is a very reputable breeder and known through out Midwest. He told me weeks ago that many of these Kamfa's can be fertile but people quit way to soon and automatically assume that their fish is sterile. He said many of these fishes need to mature fully and many Parrots that people believe are not fertile are fertile if they mature in age. Now he did not say all parrots are fertile or all kamfas are sterile but said many of these fishes can be fertile if given a few chances and time to mature.
After what I saw, I might have to agree with this just based on my own experience.
My two parrots have been spawning every few weeks, and the only successful breeding was their first attempt. Every single once thereafter has failed until they achieved this last batch.
I'm led to believe one of two things:
Option 1) Fertile male parrots have a very low success rate in fertilization. Let's do some math. Mine has spawned 14 times this year. Each spawned contained approximately 70 Eggs on average. The total fry which successfully hatched (that I know about) are 10. Four out of those 10 did not survive for whatever reason, leaving 6 behind to grow and prosper.
14 wks x 70 eggs =
980 eggs
10 fry / 980 eggs =
1% chance
6 survivors / 980 eggs =
0.6% chance
Given the averages of successful breeding, a hobbyist like myself with a fertile male parrot has a
0.8% chance for an egg to hatch successfully and the fry actually survive each year.
Less than 1% is some tough odds.
Option 2) Perhaps the maturity concept is true, and as the fertile male parrot begins to age, he becomes more fertile. So far, using that theory, I could note that the first successful breeding had 3 successful hatchlings, out of which two have survived and live with their parents still this day. The second successful breeding netted 8 hatchlings, with 4 survivors. Using that theory, that'd suggest that the next successful breeding might have an incline in the number of eggs which receive fertilization based on the father's maturity. If so, then next time they spawn during the first week of January, we should potentially see between 12-16 hatchlings come about, and perhaps 6-10 surviving fry. Another key factor here is that successful breedings took place about 10 months apart. Using that fact, we might conclude that the next breeding should take place sooner, and perhaps would be successful within 6-8 months--June through August of 2010. Additionally, the logic explained here might suggest that maturity of the fish is playing a role in the increasing odds of successful breeding.
One thing is for certain, I cannot wait to calculate these odds over the next year to see what the results are, and will report them back to the website.
I'm interested in learning more about this species from this standpoint for sure.
